Because of the format of Planck 2009, which permitted much fewer parallel session talks than in previous editions, only a small fraction of the many proposed abstracts could be accepted. Since there were many more abstracts worth a presentation than those accepted for a talk, we created a web-based poster session, open (after approval by the organizing committee) to all registered participants who paid the conference fee or whose conference fee was waived by the organizers.

Poster presentations will remain accessible from the conference webpage after the conference, and can be considered part of the "web proceedings" that also contain the slides of the oral presentations in the plenary and parallel sessions.
